MACHINE FOR SANDING MATCH-BOXES.

SPECIFICATION forming part of Letters Patent Nb. 388,582, dated August28, 1888.

Application filed May 12, 1887. Serial No. 238,019.

1'0 all whom it may concern.-

Be it known that we, CHARLES H. PRESTON and HENRY W. WHALEN, ofDetroit,-in the county of Wayne and State of Michigan, have 5 inventednew and useful Improvements in Machines for Sanding Match-Boxes; and wehereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,

r0 which form a part of this specification.

This invention relates to new and useful improvements in machines forsanding matchboxes or shucks; and the invention consists in an improvedconstruction and arrangement of different mechanical devices and theircombinationinto an operative machine, whereby the work of sandingmatch-boxes or shucks is carried out mechanically instead of by hand.

Our machine is intended to sand that part of the box called the shock,which is merely the outside shell of the box, and to save extra handlingwe prefer to attach the machine to the delivery end of the machine whichmanufactures these shucks. IV here this, however,

2 5 is not desirable, we provide the machine with a suitable feedingdevice for independent op eration, all as hereinafter described.

In the drawings which accompany this specification, Figure l is avertical central longitudinal section of our machine. Fig. 2 is a planthereof. Fig. 3 is a cross-section on the line a: a" in Fig. 1. Figs.4., 5, and 6 are perspectives of a match-box and shuck, illustrat; ingthe work our machine is intended to per- 5 form.

In the drawings, Figs. 4 and 5 show in perspective two so-calledmatch-box shucks provided with the sanding A, usually applied to oneside, either along the whole length or 0 only partly so, and thissanding is obtained by first applying glue to the surface to be sandedand then enough sand to form a rough face for striking the matchthereon. The shucks are made of thin straw-board, and are 5 deliveredfrom the box-machine in a flattened condition, as shown, and thefunction of the machine is to receive these shucks or boxes preferablydirectly from the box or shuek machine and perform the work of applyingthe (No model.)

glue and sand perfectly automatically. To this end the machine isprovided with a bed, B, provided with parallel guides C the width of theshucks or boxes apart and suitably arranged to confine them to the bed,so they may push each other endwise over the bed. V These guides areadjustable on the bed by means of the slots and setserews, as shown inFig. 2, or in any suitable manner, and are provided with spring-guidesc, which press on the shucks and hold them down, as best seen in Fig. 3.

Near the front end and underneath the bed is journaled in suitablehearings in the frame the wheel D, and underneath this wheel isjournaled another wheel, E, which dips intoa glue-pan, F, all soarranged that by a suitable rotation of these wheels the face of thewheel D will receive a coating of glue from the face of the wheel E andapply it to the shuck or boX in its passage over the bed. The bed islongitudinally slotted to expose the required portion of the under sideof the shock or box to the operation of the gluewheel D, and a suitablepressure foot or roll, G, is placed above the wheel D to insure contactbetween such wheel and the shock or box.

His the sanding-wheel, placed in rear of the wheel D. It is suitablyjournaled in the frame underneath the bed, and is inclosed in a boX, I,which contains the sand or its equivalent, and which may also beprovided with a suit able hopper for keeping up the supply of sand. Thesanding-wheel is provided with aseries of peripheral pockets orindentations, and is driven at a relatively high rate of speed, so as tothrow' the sand by centrifugal force upwardl y and against the underside of the shuck or box, so that it will embed itself into the gluepreviously applied. The shucks or boxes after passing the sanding-wheeldrop off the bed completed.

No feeding device is needed if the machine is attached to thebox-machine just in rear of the knife-cylinders which cut off theshucks, as the latter will shove each other forwardly; but where this isnot desirable or applicable we provide the machine near its forward endwith one or more sets of feed-rolls, K.

To regulate the amount of glue put onto the shueks, we place a gage-bar,L, in rear of the wheel E and secure it adj ustably to scrape off thesuperfluous glue. To keep the glue in the pot warm, we provide thelatter with any suitable device for that purpose. If the face of thewheel D is made perfectly continuous, the glue will be put the wholelength ofthe sh uck or box. If this is not required, then we use a wheelwhich has a portion of its face cut away, so as to apply the glue onlyto a portion of the length of the shuck or box, as shown in dotted linesin Fig. 1.

To adapt the machine to work on different sizes of match-boxes orshucks, we preferably provide suitable adjustments for all the partswhere it is required and construct the bed in two parts, so as to bereadily adjusted to shacks or boxes of any width.

The machine may be driven by suitable connection with the box or shuckmachine or otherwise. As shown in the drawings, the power is applied toa shaft, M, and from there is transmitted by a pinion, N, on said shaftto a pinion, O, which gives motion to a pinion on the shaft of one ofthe feed-rolls and to a pinion on the shalt of the wheel D. From thereit is transmitted to a pinion on the shaft of the wheel E. Thesanding-wheel H is driven at a relatively high rate of speed by a beltfrom a suitable pulley on the shaft of the wheel D.

Importance is attached to the intermediate glue-wheel, D, for by its usethe amount of glue applied to the shucks may be regulated so that a verythin coat can be applied, so that the same will dry in a very shorttime.

glued surface of the shuck.

What- We claim as our invention is 1. In a machine for the purposedescribed, the combination, with the gluing and sanding devices, of thebed B, formed in two parts, and the guides adj ustably seen red to saidbed, substantially as and for the purpose specified.

2. In a machine for the purpose described, the combination, with thegluing and sanding devices, of the bed B, the parallel guides, and thespring guides a, secured to said parallel guides, substantially as andfor the purpose 1 specified.

3. In a machine for the purpose described, the combination, with thegluing and sanding devices, of the bed B, the adjustable parallelguides, and the spring-guides 0, secured to said parallel guides,substantially as and for the purpose specified.
